WARNING:
You cannot replace individual fans in the thermal
management unit. If failure of a fan occurs, the entire unit must
be replaced as soon as possible.
Installing The Thermal Management Unit
You will need a flat-tipped screwdriver to install the thermal
management unit into the MSH chassis.
The unit can be hot-inserted; you do not have to power the MSH
down before installation. You should not run the MSH for more
than a short while without a working TMU installed.

With the grill at the front of the fan tray towards you and the
cut-outs in the top of the tray facing upwards, guide the unit into
the MSH chassis until it is fully home. See Figure 2-8.
2
With a screwdriver tighten the two captive screws. The captive
screws are shown removed from the unit in Figure 2-8 for clarity.

Fit the locking bar and tighten two screws fully.
